WAGON-BRAKE.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Application filed March 10, 1910, Serial No. 548,382. Renewed July 21,1911. Serial No. 639,865.

To all whom it may concern:

Be it known that I, ELMER SPIRES, a citizen of the United States,residing at ()klahoma city, in the county of Oklahoma and State ofOklahoma, have invented certain new and useful Improvements in lVagon-Brakes; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in wagon brakes.

The object of the invention is to improve the construction andarrangement of the brake shown in United States Patent No. 629,017granted to me July 18th, 1899, whereby the same may be employed inconnection with a box or body or with a hay rack, and whereby the brakemechanism will be strengthened and the efliciency of the brakeincreased.

it-h the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings: Figure 1 is a side view of a wagon runninggear showing a box or body ar -anged thereon and my improved brakeapplied thereto; Fig. 2 is a similar view with a hay rack body showingthe application of the invention; Fig. 3 is a vertical cross sectiontaken immediately in front of the brake beam and looking toward the rearof the wagon shown in Fig. 1; Fig. at is a bottom plan view of the rearend of the running gear; Fig. 5 is a vertical, longitudinal section ofthe same.

In carrying out my presentll'IlPI'OVQlnQIltS, I secure to the runninggear an upper cross beam 1, on the ends of which are secured hangers 2having a lower cross bar 3 secured to their lower end. On the ends ofthe upper cross bar are hooks 41 engaging links 5 adapted to engagehooks G on the wagon box or smaller hooks 7 on the frame of the hayrack, as clearly shown in Figs. 1 and 2. To increase the rigidity of theapparatus and enhance its efficiency, I employ fastening rods 8 whichhave their rear ends bolted or otherwise rigidly secured to the axle, asshown. The threaded forward ends of the said rods are inserted throughsuit able apertures formed in the lower cross bars and on said ends aremounted clamping nuts 9 which are turned home against the opposite sidesof the cross bar and thereby rigidly hold said bar against forward orrearward movement and, consequently, maintain the brake shaft at a fixeddistance from the wheels so that the stroke needed to bring the shoesagainst the wheels will remain constant.

In the upper side of the lower cross bar of the brake supporting frameis formed a longitudinally disposed groove or channel 10 in which isloosely mounted a brake shaft 11, said shaft being held in said grooveby means of clips 12, or other suitable fastening dcvices. The ends ofthe brake shaft 11 are bent at right angles and project rearwardly toform brake shoe supporting arms 13 to the outer ends of which areloosely connected brake shoes 1 1. The shoes are preferably formed ofsteel plates and are provided on their outer edges with right angularflanges 15 which engage the outer edges of the tire of the wheel asshown while on their front sides are formed pairs of apertured ears orlugs 16 with which are pivotally connected the outer ends of thesupporting arms 13.

The peculiar form of the brake shoes exerts a braking action against theside of the wheels as well as against the treads thereof so that thewheels will be effectually held against rotation.

The central portion of the brake shaft 11 is formed into an upwardlyprojecting crank arm 17 which is connected by a link to depending crankarms 19 on an operating shaft 20 which is journaled in suitable hearingson the running gear. Upon one side of the operating shaft 20 is formedan upwardly projecting crank arm 21 connected by a rod 22 to a handlever 23 arranged at or near the front end of the wagon box. The lever23 carries a pawl 24. which engages the teeth of a segmental rack 25provided with a gear 26, as shown in Fig. 1.

In Fig. 3 of the drawings I provide two separate brake shafts 11, havingtwo upwardly disposed crank arms 17 the horizontal portions of saidshafts being mounted in channels 30, in the lower cross bar 3, saidcrank arms 17 having their upper ends connected to links 14, on thehorizontal portions 20, of a projecting crank arm 21.

The brake lever 23 and its connections just described are adapted. foruse in connection with an ordinary'wagon body and are practically thesame as shown in my previous patent hereinbefore referred to.

In addition to the operating mechanism just described, I provide asupplemental operating mechanism for use in connection with a hay rackwherein the before mentioned operating mechanism could not be readilyemployed. The supplemental op erating mechanism referred to comprises arearwardly extending operating rod 27 the forward end of which ispivotally connected to the crank arm 21 on the end of the operating rodor shaft 20 of the brake mechanism. To the rear end of the operating rod27, is connected an operating cord or cable 28 which extends upwardlyand passes over a guide pulley 29 revolubly mounted in a bracket 30 onthe upper end of a post or standard 31, the lower end of which isreduced and is detachably engaged with a suitable keeper 32 secured tothe frame of the hay rack. After passing through the guide pulley 29,the cable or cord 28 extends forwardly to the front end of the hay rackor to the top of the load within convenient reach of the driver who bymeans of said cable may operate the brake when desired. On the crank arm21 of the operating shaft 20 are secured sockets or keepers 33 withwhich may be engaged the lower ends of an extension not shown but bymeans of which the crank arm may be extended upwardly to any desiredlength.

By providing the supplemental brake operating mechanism as herein shownand described, in addition to the regular brake operating mechanism fora wagon body, the brake may be operated by the driver on top of a loadof hay as readily as when sitting on the seat of the wagon. In makingthe change from one operating mechanism to another, as when the wagonbody is removed and replaced by the hay rack, the

inner end of the connecting rod 22 is disconnected from the crank arm 21of the operating shaft 20 and the links 5 disconnected from the hooks 6of the wagon box after which the box may be removed from the runninggear and the hay rack placed thereon. The operating rod 27 is nowconnected with the crank arm 21 of the operating shaft 20 and theoperating cord or cable passed to the guide pulley 29 and extendedthrough the front end of the hay rack in position to be taken up on topof the load, whereby the driver may operate the brake from his positionon the load.

From the foregoing description, taken i connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Having thus described my invention, what I claim is The combination withthe running gear of a wagon, of an upper cross-bar secured thereon, alower cross-bar suspended from said upper crossbar, and having a channeltherein, fastening rods secured to the axle of the running gear andhaving their forward ends rigidly secured to said lower cross-bar, apair 'of brake shafts adapted to rotate in said channel and havingupwardly extending arms at opposite ends, a crank shaft having ahorizontal portion provided with links to which are attached the upperends of the inner arms of said brake shafts, brake shoes on said outerarms of said brake shafts, and a rod connected to the brake shaft havinga lever connected therewith.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
